Define Nodata

inputRaster

(Required)

The input raster, specified by either an item ID, image service URL, cloud raster dataset, or shared raster dataset.

Syntax: JSON object describes the input raster. At least one type of input needs to be provided in the JSON object. If multiple inputs are given, itemId will take priority.

Example:

1
2
3
{"itemId": "<portal item id>"}
{"url": "<image service url>"}
{"uri": "<cloud raster uri or shared data path>"}

nodata

(Required)

Specify the NoData value for each band. Each band can have a unique NoData value defined, specify a range of values displayed for each band, or you can use the same value for all bands. If a range of values are provided, values outside of this range will be classified as NoData. When working with composite bands, the range will apply to all bands. For more information, see documentation on NoData values.

Example:

1
2
3
4
5
{"noDataValues": [0]}

{"noDataValues": [0, 255, 0]}

{"includedRanges": [0, 255]}

queryFilter

(Optional)

A SQL statement to select a specific raster in the mosaic dataset. Only the selected rasters will have their NoData values updated.

numOfBands

(Optional)

The number of bands in the mosaic dataset. The default value is Null.

compositeValue

(Optional)

Specifies whether all bands must be NoData for the pixel to be classified as NoData. Default is Null.

f

The response format. The default format is html.

Values: html | json | pjson
